ROOF FLASHING.

. Application filed April 6,

To all whom, it may concern Be it known that I, SHERWOOD BADGER FAISON, a citizen. of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Roof Flashings, of which the following is a specification.

This invention relates to roof-flashings that are adapted to water or weather proof the joint between the vertical face of the firewall of a building and the adjacent in her edge of the main roof-covering, and its object is toprovide a metal-incased Wooden strip or other suitable re-inforcing filler or core with an upper rim or vertical extension and'which is adapted to be nailed, together with the Lip-turned inner edge or flashinginargin of the said main roof-covering, into the face of the said wall for securingthe flashing in place, with a firm and tight l water or weather proof joint and without liability of the said filling of the said flashing-strip to materially split or fraoturethat .would otherwise loosen orweaken the flash- .joint and. permit leakage therethrough. Another feature. of the invention herein is to providethe said metal-incased reinforcin g wooden strip or filling with a tenon-andfmortis'e joint, between "meeting lengths or sectionsthereof, to obviateloose joints and to otherwise rigidly bind the meeting or "contacting ends "of fthe-s aid sectionsftogether, 'a1ways proof against alinement breakage. 1 V

The details of structure and method of application will'be ruu described herein- .after and then m ore particularly pointed out inthe claims that follow same.

In the accompanying sheet of drawings .Figu'rel is a cross-SectionQtaken on line -.1,-1, of Fig. 2,01? a roof-flashing fastening 'orre-inforcing strip embodying 'one form of .my invention and showing it appliedito the desired face of a fire or other brick. wall, the'latter and the upturned flashing-member ofthe roof-coveringrbeing shown in section, including, also, the fmortarbetween the courses of brick, the plastic-fillerin the gutteredupper part of said'fastening-strip gether with the-roof-boarding or deck on which-thesaid main roof-covering is laid; Fig. 2, a fragmentary front elevation of the improved flashing-strip herein, showing it 1923.

wall and including a tenon-and-mortise joint in abutting or end-to-end sections or lengths of the said strip; Fig. 8, a front elevation of one brokeirofi' end of the flashing fastener-strip herein, it being the end containing the mortise or socket for the joint between sections of strip; Fig. 4, a front elevation of the broken-oil tenon-end of the flashing fastener-strip that is adapted and intended by me to coact with the said mortised-end seen in the adjacent view (Fig. 3) to the left; and Fig. 5, a cross-section (out of line with the nail) of the preferred form of filler or core and metal sheathing therefor, the latter having but an upright flange along its fore upper edge and -no lower flange or extension such as that in In Fig. 1, I have shownan ordinary wall made up of bricks 5 laid in horizontal courses, with the mortar or cement filled joints 6 between them, as customary.

7 indicates the main roof-covering which may be of composite or other desired material and laid upon the boarding or roofsheathing8 whose inner edge 9abuts the desired co-operating face of the wall.

10 indicates the upturned inner edge or desired margin of the said main roofcovering 7 and constitutes the flashingproper, or that part of the buildingstructure which makes joint with the said face of the wall. This flashing usually rises to a height equal to a little more than several courses of brick, as best shown in Fig. 1, and, along its upper margin, a closing or fastening strip 11 is used.

Ordinarily, the said fastening-strip 11 is made of wood and similar to an ordinary lath, but the driving of suitable large-size nails 12 through it has caused it to split and become defective for the water and weather proof service intended and expected of it. To rectify such a serious and material defeet is one of the essential features of my invention herein and I do it by encompassing the strip 11 with a metal sheathing 0r casing 13 which, (in one form'herein), has a pendent rear flange or projection 14 and an upright fore flange or projection 15, the said rear flange 14: contacting with the face of the wall and the fore flange 15 providing a gutter or receptacle that extends over he flush upper edge of the upright flashing 10, and is adapted and intended to receive the filling 16 of plastic material that seals the upper part of the flashing against any and all leakage, and thus being water and weather proof, as well as dust and dirt proof as to afford proper drainage to the outer face of the flashing-strip, whence such drainage descends to the outer lower corner 17 of the strip and drips therefrom, the pendent rear flange 14 adding protection, if any is needed, against any possible leakage upwardly into the joint by capillary attraction or seepage.

. In Fig. 1, I show the metal sheathing or casing 13 as being constructed of several corresponding members, which are easily made and easily assembled on the wooden filler ll. Each of these corresponding parts has a right-angled bend along one edge and a U- shape one along the other edge, the U-shape bend 18 of the upper fore-flange of the outermember being turned or disposed inwardly and the U-shape bend 19 along the lower edge of the inner-member being turned or disposed outwardly, while the said rightangled bends 20 and 21 in the said several corresponding members are the reverse. It is quite obvious, however, that the said metal casing 13 can be and is preferably formed 7 or shaped out of a single piece of material,

if desired, as I do not limit or confine myself tothe two-member form shown and described herein. When made of a single piece it is shaped as shown in Fig. 5, there beingno lower flange-extension 14, but the upper flange-extension is the same as in Fig. 1.

The fastening-strip 11 is preferably made of wood, but it may be made of cement or similar material. lVhen placed within the metal casing or sheathing 13 it forms a filler or core strip 11 that will not warp or break, or become otherwise impaired in any ma terial or defective way for the best use that a flashing-strip can be put to.

The metal-covered filler-strips will be made ordinarily in lath lengths, but their actual lengths for use will be more or less varied to suit conditions.

lVithout the metal sheathing the wooden fastener-strips cannot be securely held in place, as only small nails can be used on account of their easy cracking and splitting, when large and adequate strong nails should be used to properly and permanently secure the flashing in workmanlike and water and weather proof condition on the Wall. Besides, the unarmored wooden strip is subject to curl at its ends and thereby draw or pull away from its anchorage on the face of the wall, and much more trouble and njury result. The metal-sheathed strip here- 1n can and will prevent any curling, but, to make that feature doubly sure and to positively hold the composite armored strips in perfect alinement in every way, I provide a tenon-and-mortise joint between the meeting or abutting ends of these strips, the

tenon and its companion mortise being easily formed by extending the wooden filler-strip 11 beyond the end of its metal sheathing the desired distance to constitute a suitable tenon 22, and thereby bringing its opposite end the same distance inwardly from the other end of the said metal sheathing, the wooden filler-strip, initially, being the same length'as that of the metal sheathing and thus leaving a cavityor socket to form a mortise or connecting-pocket 23 for the said tenon 22 when two armored strips are brought together, end'to end, in the operation of etting and fastening the flashing in place on the wall for making a closed or sealed joint for the roof.

Sheet-metal flashing alone, as commonly used, is difficult to hold in'place on the wall and to pro erly point up, because the mortar cracks an falls out and lets water enter back of the flashing, all of which is an expensive operation, especially in old brick walls where raking out of joints is necessary to receive the flashing. With metalcovered wooden filler cores or strips there is no need to rake out joints, and any size nail, necessary to hold the strip and flashing in place, is used.

Besides, the metal-sheathed strip always remains in its proper place, and, therefore, outlasts other forms in use, and at much less cost, as a result. form of recesses or steps in the face of the wall for the flashing, because it always follows the line parallel with the roof, which is of much importance in the jointing of a roof.

The upright inner portion or flashing 10 of the roofing is stuck in place'on the wall by means of the usual adhesive.

It will be seen that, in the event the wooden filler-strip 11 should split within the metal casing or sheathing, no impairment would take place, for the very obvious reason that, while splitting, the resultant expansion, due to the driving-action and It eliminates the old I 2.
